This millet supports UWB, which is not confirmed to be a specific industrial chain partner. During the country, the company is currently doing UWB companies and the above manufacturers. It is worth mentioning that there is a large number of small and medium-sized entrepreneurial teams in the development of UWB solutions, mainly for indoor high-precision positioning and smart home, intelligent parks, intelligent buildings and other scenes. At present, in addition to Apple and Xiaomi, Samsung is also very optimistic about UWB technology, which will become one of the next generation of wireless communication technology that can change the rules of the game.

As Xiaomi performs in the public technology demo, under the application scenario of smart homes, UWB technology can perform a sense of ranging from mobile phones to the core, minimizing the dependence of the traditional industry, can realize mobile Internet access Remote control, intelligent unlocking function. In this scenario, relatively frequently invoking smart home control software, UWB technology application simplifies interactive flow between users and smart home devices, and is a major innovation application for smart home systems. In fact, with the assistance of mobile phones, the functionality of UWB technology is still more than this. According to incomplete statistics, the iPhone 11 has applied UWB technology since 2019, in addition to the "remote control + open smart door lock" function of Xiaomi demo, there are many new features. for example:

1) Assist AirdroP (ie, email delivery) precise positioning data transmission objects. AirdroP on iPhone 11 has a new feature that can be sorted by people around them so that users can choose the most recent person to transfer data.

2) Real-time positioning Real-time Location. In the case where there is no GPS, such as the underground parking lot of the airport, UWB can help position, users can share it to the webmark driver, inform yourself, so that the driver finds passengers.

3) Car key carKey. Apple launched a CarKey function in iOS14, sharing the car key through the mobile phone, the initial partner is BMW, which uses ultra-wideband UWB technology.

According to recent media disclosure, the object tracking device will be Apple's next UWB technology application. It has been reported that Apple plans to release a new small peripheral Airtags in the first half of this year, with UWB wireless features, attached to objects such as mobile phones, wallets, keys, etc., which can be easily found via the Find MY app on the phone. In summary, the application scenario of UWB technology has been unlocked from traditional industries to smart home, intelligent office, smart city, smart transportation, consumer electronics and other fields.

Based on the mobile phone market, UWB technology has begun to highlight the explosive trend of the consumer electronics market. It is understood that the sales of iPhone 11 in 2019 is about 40 million, that is, only Apple has driven 40 million UWB chips in 2019, which has reached the sum of the sales of UWB chips in the past few years. In 2020, as Samsung and Xiaomi announced that the UWB technology represented in the mobile phone, the consumer-based application of the mobile phone was gradually approached. Before you have any brokerage, UWB technology has been mature, the market is available or exceeded, and the consumer application is undoubtedly the most imagination in numerous applications in numerous applications.
